While some fans of the Marvel Cinematic Universe assign their favorite characters' zodiac signs based purely on their personalities, there are some characters whose birthdays have been established in the franchise's canon.

Although not every Avenger has an official MCU birthday, some can be roughly deduced thanks to the timeline of the movies. On the other hand, immortals like Thor are near-impossible to assign a canon date. In any case, discovering the official astrological signs of the Avengers is interesting, as it gives insight into a character, and it’s fun to see if their traits match their sign well or not.

Even though there are several Avengers whose birthdays remain a mystery, looking at the characters that are given canon dates can allow audiences to see them in a new way, and examine the legacy they have left in the MCU, a theme explored in Black Panther: Wakanda Forever.

Vision - Taurus

Vision's birth isn't exactly traditional. He's not born, but made by Tony Stark and Bruce Banner in the MCU. As this occurs in Avengers: Age Of Ultron, the audience can surmise that his "birth" happens in early May 2015, making him a Taurus. Tauruses are marked by their steadfast nature. They are often thought of as stubborn, but they're incredibly patient.

Vision has a childlike innocence to him at first, but he proves himself patient and reliable in all of his interactions with the Avengers as he follows the leads of others, learns their methods, and struggles to adapt to sudden changes.

Black Panther - Taurus/Gemini Cusp

T'Challa sat on the throne in Black Panther

In the MCU, T’Challa was born on May 21st, 1980. This technically makes him a Gemini, but since the date is right on the cusp, it’s important to look at both Taurus and Gemini traits to see which one fits. T’Challa definitely has many Taurus traits, and this sign is known for being practical and reliable, which makes sense as T’Challa is a leader that many people rely on.

But, since Taurus is ruled by Venus, they also have a soft, romantic side to them, just like T’Challa. The Gemini in T’Challa’s sign makes him more adaptable than the typical Taurus, however, and he always seems ready for anything.

Iron Man - Gemini

Born on May 29th, 1970, in the MCU Tony Stark is a Gemini, which is a perfect fit. Geminis are known to be outspoken, but they are also very intellectual and relentless in their search for information. They also love to share what they know with others and are very quick-witted. Their wit is a trait they are proud of, as they are known to be the life of the party.

The Gemini sign sums up Tony's unmistakable traits in the MCU. Geminis are somewhat mercurial and can have two sides to them, shown through Iron Man’s outward confident and witty persona, and the more internal side that is wracked with guilt and self-doubt.

Captain America And Nick Fury - Cancer

Captain America was born on July 4th, 1918. While his Independence Day birthday is on the nose, Cancers are people who like to take care of others and have a strong sense of loyalty, which translates to Cap's arc in the MCU, which started with his devotion to his country. Cancers are also known to have an introverted side, as seen in how Steve often keeps his feelings hidden away while giving off a very put-together front.

The man who brought the Avengers together, Nick Fury, shares Cap's July 4th birthday, as revealed on his ID in Captain Marvel. Though the two have different approaches to helping the world, they share motivations. Fury's introverted side is shown in that he only trusts a select few people, and it's his career as a spy that has made him unlikely to tell everyone the whole truth all the time. Not many MCU characters share official zodiac signs, so it's interesting that these two characters with often opposing views do.

Spider-Man - Virgo

Peter Parker removes his mask in Spider-Man: Far From Home

Peter Parker was born on August 27th, making him a Virgo. This methodical type is known for taking joy in helping and taking care of others. They are a sign that is associated with duty, and they are always looking out for the greater good. As such, Virgo is a perfect astrological match for Peter Parker.

He is always about protecting others and living up to his duty as a friendly neighborhood Spider-Man. Virgos can also be quite obsessive about projects, something Parker can relate to as a science nerd. Moreover, Virgos often have an innocence about them that is endearing, which Parker demonstrates in Captain America: Civil War's airport fight.

Falcon - Virgo/Libra Cusp

Steve Rogers gives Sam Wilson the Captain America shield in Avengers: Endgame

Sam Wilson's birthday is September 23rd, 1978, as revealed in a promotional video released by Marvel for Latin American countries. That birthdate puts him at the very end of the Virgo season, on the cusp of being a Libra, and both signs are actually a great fit for Sam.

Though they're often recognized for their organizational skills, Virgos are the nurturers of the zodiac who tend to take care of their friends, just as Sam does during his Captain America: The Winter Soldier introduction. However, Sam also has a lot of Libra traits, including his charm and tendency to work with a partner, as well as his strong sense of justice.

War Machine - Libra

James Rhodes, known as Rhodey, was born on October 8th, 1968, which makes him a Libra. This sign is known for being more focused on working with others than individualism, which makes sense given Rhodey's status as part of one of the MCU's best superhero duos, alongside his best friend Iron Man.

Libras are also associated with the Scales of Justice and being objective; they want to do what’s best for everyone and care about fairness. This is very in line with Rhodey’s personality, and the ways that he is often one of the most objective members of the team, always thinking about justice and logic.

Black Widow And Doctor Strange - Scorpio

Natasha Romanoff was born on November 22nd, 1984, making her a Scorpio, and the sign is a great fit. Scorpios are serious types who don’t like to waste time, and are great at gathering secrets, which perfectly matches Natasha's spy skill set. Known for their ability to get to the bottom of things, Scorpios are one of the fiercest signs in the zodiac, and a perfect fit for Black Widow.

While the two characters seem very different, they both exemplify their zodiac sign well. Scorpios are stubborn and determined, and they tend to go after what they want in life, as Doctor Strange did, stealing magical books to complete his training faster.

Hulk - Sagittarius

Bruce Banner was born on December 18th, making him a Sagittarius. People of this sign are known for being truth-seekers always looking for knowledge, and are often called the philosopher of the zodiac. They are ruled by the planet Jupiter, which is all about philosophy, truth, and travel.

Sagittarians tend to be very enthusiastic when pursuing information and learning, which sounds just like Banner. While there have been some changes to Bruce Banner since Endgame, he is still all about scientific learning and discovery. When first attempting to get rid of or tame his Hulk side, he traveled the world in search of a cure and has since visited many planets.

Hawkeye - Capricorn

Clint was born on January 7th, 1971, making him a Capricorn. This sign is known for being about hard work, and for being determined and ambitious. This makes sense for Hawkeye, as he has no superpowers, but has worked hard to be able to hold his own alongside those of the Avengers who do.

Capricorns are also known for being practical and stubborn, two traits that Hawkeye often embodies. The sign are all about achieving their goals through pragmatism and hard work, traits MCU Hawkeye exemplifies as he never gives up. No matter how often he wants to retire from the job, he puts in the work to be the hero the world needs, even when they don't appreciate him.

Winter Soldier - Pisces

Bucky talks to Steve in Avengers Infinity War

Bucky Barnes is a fan-favorite character who was born on March 10th, 1917, and this makes him a Pisces. Pisces are known as the chameleons of the zodiac, and are often emotional individuals with a strong moral compass.

While Barnes might not have always been able to act under his own morals, given his traumatic experiences as the Winter Soldier, his experiences before and after this time prove that he's a considerate and heroic person. Pisces are also known for putting others above themselves, which makes sense given how Bucky used to take care of Steve Rogers before Steve received his Super-Soldier serum.
